The type of resin you're after is "Wing Skinning" type and is as thin as water. "Laminating" resins are thicker. If you go back to Peters (HS93) post, the one he shows, "Aeropoxy" is ideal.

Yes, thanks Ian, I have it now.
Fortunately my local model shop does stock this, so if you think its ideal
and not too thin then I'll give it a go.

Many thanks.

I have now stripped my Fireboat, and found the weak points where it had let in water.
Actually most of the hull does look in reasonable condition considering that the boat is at least 40yrs old.

I have applied 3 coats of sanding sealer in readiness for the glass fibre cloth and resin which will
be going on tomorrow. The cloth is 48g weight and the resin is Z Poxy 24hr finishing resin.
I have included a photo of the cloth which is quite thin and fine. Have tested it on a piece of ply
and it does go on very easily with a fine, smooth finish once dry.

Before you go any further Nordlys, the chine stringer needs to come off, 2 reasons, it will be difficult to get the cloth round it, but more importantly, it's fitted in the wrong place.

Regards Ian.

Really? Can you enlarge on that please?
Not hard to remove but where does it belong?

I hadn't paid any attention to that at all......

Morning.
Ok, I see now where the stringer should be - how odd that I hadn't noticed this before.
I wasn't actually thinking of fibre glassing on the sides of the boat, just on the
underside of the hull, rightly or wrongly.

I am wondering whether the slender modelling pins (brass) that I use will be strong enough to
penetrate thru' the glass fibre & cloth?

I would be interested if anyone can tell me of a supplier for these modelling pins ie. the preferred type.

I have got as far as laying on the first layer of glass cloth and resin. Easy enough to
apply but have to say that it's looking a bit rippley right now -I think I'm loosing what was a decent
flat plywood surface and now have this uneven surface which I hope rubs down into something
reasonable!
At least it will be watertight with some strength.
A lengthy process with this 24hr poxy resin.

On the opposite side I seem to have achieved a better finish by
following Pompebled method from an earlier post (I believe).

I just applied a layer of resin to the hull and layed the glass cloth on,
smoothed it into place but did not add any further resin to the cloth.
No runs or ripples so far.
Hope this may be of some interest to anyone attempting to fibre glass hull
for the first time. Techniq

Didn't try pulling the resin through the cloth with a squeegee then? (post #20). Idea is to get the cloth as close to the wood skin as possible.

Regards Ian

Nordlys · « **Reply #36 on:** September 08, 2012, 04:23:48 pm »

Yes, did that with a thinnish piece of plastic card as you suggested. For some reason had
more success on 2nd side than 1st.
Will have to work the 1st side more extensively to smooth out the ripples.

Would you put on more than one layer?

Bit of a learning curve for me.

Thanks for your help tho'.

Circlip · « **Reply #37 on:** September 08, 2012, 07:47:23 pm »

No more than 1 layer of cloth.

Regards Ian.

If you're getting ripples, you're doing things wrong- it should go on absolutely flat, and only the slight weave of the cloth should need to be filed with resin to get a perfect smooth finish. The answer is- always practice on something non-critical before committing to a model that is valuable to you.

I was going to post a couple of pictures of the progress
I have made with fibre glassing the hull of my fireboat but I can't upload to photobucket
Keeps saying 'error in upload'.
3 times I've tried but it won't have it? Im following same procedure as I always have,
so thats it for me!

Just found out - its a Photobucket error which they say they
are working on.
Ahh. Patience I lack......

Photobucket now up again. So here are a few pictures of the progress
made on fibreglassing my fireboat hull.
Two coats of Halfords red primer and three coats of
Halfords Vauvhall Burgundy Gloss now drying in the sun.

I wonder what all you experts think of the finish?, one side is slightly better than the other- thats
my learning curve.
The final colour Burgundy is a bit different to the bright red on most Fireboats? I think
it will look ok once the sides are painted black with a white waterline.
Yes?

Lovely colour.

Perhaps Stavros can advise on the ripples. I should imagine there's still time for a bit of sanding and an application of very fine filler.

gwa84the2nd · « **Reply #43 on:** September 16, 2012, 12:51:17 am »

use filler primer then flat with wet and dry starting with about 800 and work your way to the finer grades always using a block on the flat serfises should get it as smooth as

Can you give the paint code for that burgundy paint?

Subculture · « **Reply #45 on:** September 16, 2012, 10:44:09 am »

If you have some resin left, you could mix it with some micro balloons to make a tough, waterproof but easy to sand filler.

Nordlys · « **Reply #46 on:** September 16, 2012, 11:07:51 am »

The paint is a Halfords spray Vauxhall Burgundy Red and
a code that I have found from their website says:
Compatible to Vauxhall manufacturers code 78L, 567
Nothing else on the can.....

Getting rid of the ripples is going to mean going through the glasscloth.

Regards Ian.

Nordlys · « **Reply #48 on:** September 16, 2012, 11:57:02 am »

Right.
With the boat in front of me the finish is actually not too bad, yes there are a few
ripples and a few humps after the fibre glassing work. I thought I had
rubbed it all down to very smooth surface, but the finish paint coat
does enhance the few flaws.
I doubt if I would go as far as sanding down through the cloth now though.
I'll just have to live with this finish, it's underwater mostly!

It has been an interesting lesson in finishing for me and I hope the thread hasn't been
a bore for all the experts on this site who have offered some very useful techniques.

I'm a bit lost with the use of micro balloons -(subculture)?

Nordlys...

Subculture · « **Reply #49 on:** September 16, 2012, 01:21:56 pm »

Microballoons are a filler made up of tiny glass spheres. You mix them with the resin, and they bulk it out, making it lighter and easier to sand, also reduce shrinkage which is very low with epoxy resin anyway.

You can use microballons with polyester resin and even cyano glues, so they have lots of uses. Colloidal silica is another filler you can add, which is a little easier to sand.
